The process of intense oxidation of various fuels with oxygen is called combustion. The chemical composition and calorific value of the fuel are two basic characteristics of the fuel. Where X——— is any component of the gas; When performing thermal calculations, they must be converted into supplies.

Referred to as coal gas fuel gas. It is a mechanical mixture of gases such as CO, H 2 , CH 4 , C 2 H 4 (including C n H m )H 2 S, CO 2 , SO 2 , O 2 , N 2 , H 2 O, among them CO, H 2 , CH 4 , C 2 H 4 , and H 2 S are combustible compositions, others are incombustible compositions. CO, H 2 , C 2 H 4 , CH 4 are beneficial constituents, H 2 S, CO 2 , SO 2 , O 2 , N 2 , H 2 O, and the like are harmful compositions. The higher the content of the beneficial composition, the better the quality of the gas. The content of each component in the gas is expressed by volume percent, and there are two expressions of a wet component and a thousand component. The wet component refers to a component including moisture, which is expressed by:
CO W +H 2 W +CH W 4 +C n H W M 3+H 2 S W +CO W 2 +SO W 2
+O W 2 +N W 2 +H 2 O W =100% (1)
Wherein CO W , H W 2 ... H 2 O W ---- is the volume percentage of components such as CO, H 2 ... H 2 O in the wet gas.
A dry ingredient refers to a component that does not include moisture, and is expressed by:
Co d +H d 2 +CH d 2 +C n H d m +H 2 S d +CO d 2 +SO d 2
+O d 2 +N d 2 =100% (2)
Where CO d , H d 2 ... N d 2 ——— is the percentage of CO, H 2 ... N 2 and other components in the dry gas.
The dry components of the gas can be found in the literature. Since the gas contains moisture when it is burned, the dry component should be converted into a wet component during thermal calculation. The conversion formula is: 
q d H2O ———The saturated water vapor content absorbed by a gas of 1 m 3 thousand at a certain temperature.
Liquid and solid fuels are mainly composed of organic elements such as H, C, O, N, and S, and also contain ash (A) composed of mineral impurities such as SiO 2 , Ai 2 O 3 , Fe 2 O 3 , CaO, and a certain amount. Moisture (W). Among them, C, H and organic sulfur are combustible compositions, others are non-combustible compositions, C and H are explosive compositions, and O, N, S, A and W are harmful constituents. Liquid and solid compositions can be determined by industrial analysis or elemental analysis. Industrial analysis determines the moisture (W), ash (A), volatile (V) and fixed carbon (C) content, and elemental analysis determines the weight content of each composition. The higher the content of the beneficial composition, the lower the harmful composition content, and the better the quality of the fuel. The composition of the liquid and solid fuel is generally expressed by the weight percentage of the composition, and there are four expressions of the supply component, the dry component, the combustible component, and the organic component. Can be expressed as follows:
Ingredients C op +H op +O op +N op +S op
+A op +W op =100% (4)
Dry ingredients C d +H d +O d +N d +S d +A d =100% (5)
Combustible component C c +H c +O c +N c +S c =100% (6)
Organic ingredients C o +H o +O o +N o =100% (7)
Let X be any composition, and the conversion relationship between them is:
